Start TLS

Upgrade a regular net.Stream connection to a secure tls connection. See socks5-https-client for use-case.

Based on a version by Andris Reinman, itself based on an older version by Nathan Rajlich.


The only method, startTls, returns a SecurePair and takes a Socket and an optional callback called on the secure event of the pair.

var net = require('net');
var startTls = require('starttls').startTls;
var port = 21;
var socket = net.createConnection(port);

socket.on('connect', function() {
    var securePair = startTls(socket, function() {
